insects through the screens 7 and into the housings 21 and 22. This suction is manifest in the compartments 16.

However, in order to aid the removal of the insects from the vines, I provide pipes 23 carrying compressed air and terminate these pipes adjacent to the openings 5 and 6 (see Figures 1 and 3). The pipes are connected to a common feed pipe 24 (see Figure 1) leading from a storage tank 25, and this tank is kept filled with compressed air by an air pump indicated generally at 26 which is operated by the shaft 17. The compressed air issuing from the outlet ends of the pipes 23 flows against the vineswithin the compartments 16 and aids in removing. the insects from the vines.

The means for killing the insects comprises two circular screens 27 and 28, the screen 27 being placed in the housing 21 and the screen 28being placed in the housing 22. 'These screens are carried by the shaft 17 and rotate therewith. The mesh of the screens is such as to permit the insects to be sucked therepellers 19 and 20, yet the rotation of the screens is at a sufiicient speed to kill themsects as they are being sucked through the screens. y

In Figure 2 I showhow the housings 21 and 22 empty into verticallyextending outlets 29 and 30. The insects which are killed by the screens 27' and 28 are forced into the outlets 29 and 30 and are then expelled into the air. In this way the necessity for the sacking of the insects is done away with.

Although I have shownand described one embodiment of my invention, it is to be understood that the same is susceptible of various changes, and I reserve the right to em-f ploy such changes'as may come within the scope of the claims hereto annexed.

I claim: V 1. A traveling insect apparatus, includ ing a suction chamber, having inlet and discharge openings,'means for producing a draft throughthe inlet opening, a frame hinged above the inlet opening, flexible curtains dependent from said frame and forming the walls ofa suction hood to direct the air draft through the foliage which harbors the insects, and discharge nozzles for compressed air for directing the air against the foliage enclosed by the suction hood. V

2. In an insect killing machine, a suction chamber, means for sucking air through the chamber, and arevolving screen made of sufhciently fine mesh" for. killing the insects as they are drawn through the screen by the suction. I i An insect killing machine comprising a hood for receiving foliage, means for sucking'air from the hood; for carrying insects therewith,- and a revolving screen inter-posed in the, stream of air. made'ofsufficiently revolving screen for preventing foliage and foreign matter from striking the revolving screen.

5. In an insect killing machine, a passageway for conveying insects, a propeller for causing air to move through the passageway at aspeed'sufiicient to carry insects, and a revolving screen extending across the passageway made ofsufliciently fine mesh for killing the insects as they are forced through the screenby the suction.

, 6. An insect killing machine comprising a casing having openings in its side walls, hoods having flexible sides positioned adja cent to said openings, 2. separate air passage way communicating with each opening, means for sucking air through the openings, and rotatable screens extending across the passageways for killing theinsects, the insects being discharged from the machine by the air.

7 An insect killing machine comprising a casing having openings in its side walls, hoods having flexible sides positioned adjacent to said openings, a separate air passageway communicating with each opening, means for sucking air through the openings, rotatable screens extending across the passageways for killing the insects, the insects being discharged from the machine by the air, and means for conveying compressed air to the hoods for aiding in dislodging the insectsfrom the foliage.

8. An insect killing machine comprising a hood for receiving foliage, means for withdrawing air from the hood for carrying insects therewith, a movable screen interposed in the stream of air made of sufficiently fine mesh for killing the insects as they are forced through the screen, and a conduit for conveying'compressed air to the hood and discharging the same adjacent to the ground for aiding in dislodging the insects from the foliage.

9. An insect killing machine comprising a hood for receiving foliage, means for withdrawing air from the hood for carrying insects therewith, a movable screen interposed in the stream of air made of sufficiently fine mesh for killing the'insects as they are forced through thescreemand a conduit for" conveying compressed air to the hood and discharging the same adjacent to the ground for aiding in dislodging the insects from the foliage, and for directing the insects toward the hood outlet.

. lO. All i nsect killing machine comprising drawing air through the latter, rotatable V screens extending across the passageways for killing insects withdrawn fromfollage, and means for conveying compressed air to the hoods and discharging the same adjacent to the ground for aiding in dislodging the insects from the foliage.
